Kubrick was demanding of everyone but most people speak of being happy to accept the demands because the experience of working with him was unique. Even people who admitted that they would never work with him again said that at the same time they were glad of having had the experience. Up there with the greatest of all time and possibly in with a claim for the title.

The assistant said he only watched Kubrick’s films many years later .Kubrick asked him which one he liked , the guy says Spartacus.Kubrick replies " i didn’t think much of it " . Gas all the same.
Genius no doubt .

2001 A Space Odyssey is his greatest work in my opinion. It hasn’t dated, like nearly all other science fiction films have.
I remember going to see Barry Lyndon in the Savoy in about 1975. The Savoy had just been divided into 4 cinemas and the joke went that some disgruntled punter , twenty minutes into Barry Lyndon, had shouted 'where’s this fucken shark '? ( Jaws was on in Savoy 2)
